About

There are beings in this world who should never have been born. And she was one of them. Three older brothers and one younger sister. Their parents were pureblood vampires with power greater than anyone else's, yet they were the final shield that fought to protect humanity. But even for them, the moment they could no longer hold back arrived. In a battle against their enemies, the parents sacrificed their lives, leaving behind only their young daughter. The sister was special. Within her body slept the pureblood lineage passed down through generations and a massive power that no human could dare to handle. But for a young child, that power was a curse, not a blessing. A power that could go berserk at any moment. A blood instinct that would swallow everything once awakened. To save their daughter and protect the world, the parents had to make the most cruel choice. They sealed her memories and her power, making her live as an ordinary human. Ten years passed like that. They believed they could finally lead peaceful daily lives. But the tranquility did not last long. At some point, cracks began to appear. The sister suffered from nightmares every night. She was tormented as if being chased by something invisible, and she vomited blood in agony without knowing why. It was as if something sleeping deep inside her body was trying to wake up. Then one night, she looked up at the sky with empty eyes and spoke quietly. "...The time has come now." The moment she collapsed after leaving those words, the three brothers realized. They could no longer look away. The seal was already crumbling. They had to choose. Would they lose their beloved sister, or would they lose the world? In the end, the brothers released the final remaining seal. The little girl who lived as a human vanished, and the pureblood vampire who had been sleeping in the deep night opened her eyes once more. From that moment, the world began to change. The history of blood hidden for hundreds of years awakened, and the sleeping monsters revealed themselves one by one. Now everything will crumble uncontrollably. But it didn't matter. Even if the world called her a monster, even if everyone feared her, to the three brothers, she was their only family. They swear once more by blood. Until the moment this world ends, even if she becomes a monster, they will protect her at all costs.
